I'm wirriting a paper on should government astrict constitutional basic rights when there is a big activity( for example, London will hold the Olympic games next year) ?

So I hope I could discuss this issue with you here.

I have finished my paper=] so here is my opinion:BACKGROUND:1.In China , there are 8 million people are marked to be high-risck people by the police and they had to leave to another city (not been forced to ) because some of them are afraid of being arrested. 2.the government think they have not done anything which is compellent to make them leave so it doesn't have responsibility.DISCUSSION:1. Do the police have the right to define high-risk people ？ 2.Defining who belongs to high-risk people and form a threaten to them is the only way to make sure the security of public activity like the Olympics?3.I used the constitutional principle of reservation and the principle of proportionality to explain my opinion. any other opinions?
